WINDOW-SASH.

Specification of Letters Patent.

Patented Dec. 8, 19114.

Application filed March 13, 1913. Serial No. 754,042.

To all whom. it may concern:

Be it known that I, FRANKLIN R. Esnnaon, citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in \Vindow- Sashes, ofwhich the following is a specification.

This invention relates to new and useful improvements in window sashstructure and as its principal object contemplates the provision of awindow sash which may be readily and conveniently manipulated to placethe outside of the pane in such position that it may be cleaned from theinterior of the room.

WVith reference to the drawings, wherein, I have illustrated thepreferred embodiment of my invention as it is reduced to practice, andthroughout the several views of which similar reference numeralsdesignate corresponding parts: Figure 1 is a front elevation of theseveral parts of the invention in assembled position. Fig. 2 is avertical sec tional view of the window sash. Fig. 3 is a detail viewwith the parts of the structure broken away to more clearly illustratethe operation of the interior portion of the device. Fig. 1 is a detailperspective of the guide me. bers employed in connection with theremovable sash. Fig. 5 is a detail view in side elevation of the rollermounting. Fig. 6 is a fragmentary sectional view showing the latch forthe top sash.

Proceeding now to the description of the drawings, the numeral 1designates a rectangular window casing of ordinary and usual structurehaving the guide strips 2 and 3 on each side.

Slidably mounted within the window casing 1 are the movable framemembers of my invention designated as upper and lower frames by thenumerals 1 and 5 respectively. Interiorly of the frames 41 and 5 arearranged a pair of sashes 6 and 7 which are normally arranged to move upand down with the movable frames 4: and 5. As a means for permitting theglass panes to be manipulated so that a person standin on the inner sideof the window may have ready access to the outside of the pane for thepurpose of cleaning it, I have mounts the sashes 6 and 7 between theframes 4: and 5 in such manner that either or both of the sashes may bepartially released from the frames i and 5 and the upper ends of theinner frames 6 and 7 swung outwardly and disposed horizontally with thenormal outer face 01' surface of the sash uppermost as illustrated inFig. 2. To this end I have provided the frames 1 and 5 with the verticalguide members 8 which are preferably formed of a length of sheet metal,the longitudinal edges of which are turned or rolled and bent inwardlyas at 9 to form a T- sliaped channel within which the rollers 10,rotatably mounted on the free ends of the laterally projecting pivotpins 11 carried by the frames 6 and 7, are disposed for slidingmovement. The pins 1.1 are preferably secured to a reinforcing strip 12attached to the frames 6 and 7 by screws 13 or other suitable fasteningmeans. The innermost edge 9 of each guide member 8 is provided wlth acut away portion as illustrated in Fig. 4 to permit the insertion of therollers 10 within the channel portion of the members 8. The rollerslOare secured to the sashes 6 and 7 adjacent to their upper ends for apurpose to be hereinafter disclosed.

Tn its normal or assembled position, the frame 7 in vertical positionand in order to prevent the outward movement of the lower portion of.the same with the resultant displacement of the member 7, I provide alatch 11 mounted on the lower horizontal member of the frame 7 andarranged to engage a keeper member 15 secured to the frame 5 asillustrated in Fig. 1.

For holding the top sa. h or frame 6 against swinging movement andsupporting it in closed position at the upperpart of the member 1, Iemploy a pivoted latch 16, the lower end of which is adapted to engage asuitable slot formed in the lower horizontal member of the member 4:.The member 16 carries a laterally and outwardly extending latch tongue17 which is preferably made in the form of an L, the one leg of the Lbeing riveted or otherwise secured to the member 16 and disposed so thatthe lateral leg or latch tongue 17 is spaced from the lower horizontalframe member of the frame 4: thus permitting it to rest on the free endof the pivoted keeper member 18 mounted on the upper horizontal framemember of the frame 5. It will thus be seen that the latch member 16 inconnection with the member 18 performs the double function of holdingthe glass sash 6 against outward movement and resultant displacement andat the same time holds the sashes 6 and 7 in closed locked position.

The actual construction of the invention being thus disclosed it nowremains to describe the manner of manipulating the sashes when thewindows are to be cleaned, briefly as follows: In swinging the lowersash 7 into the position indicated in Fig. 3 the latch let is disengagedfrom the member 15 and the frame is swung outwardly being pivoted duringthis movement by the roller pins 11. As the frame is swung outwardly therollers move downwardly through the guide members 8 and the sash assumesthe position shown in Fig. 3. The sash may then be swung upwardly againbeing pivoted 011 the members 11. The surface of the glass, which inassembled position of the sash, was formerly on the outer side of thewindow is then innermost and may be readily cleaned. A similar method isemployed in manipulating the upper sash 6 and in this connection it willbe observed that the frame 6 may be dropped to the bottomv of the windowframe 1 and the member 7 raised to the upper portion of the member 1,thus enabling the operator to more conveniently clean the window.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe preferred embodiment, is

Copies of this patent may be obtained for five cents each,

the most eflicient and practical; yet realizing that the conditionsconcurrent with the adoption of my device will necessarily Vary, Idesire to emphasize the fact that various minor changes in details ofconstruction, proportion and arrangement of parts may be resorted to,when required, without sacrificing any of the advantages of myinvention, as defined in the appended claim.

Having thus described my invention, what claim as new and desire tosecure by Letters Patent is as follows:

A device of the character described comprising a window casing, a sashframe slidably mounted therein, guides arranged vertically Within saidframe member formed from strips of sheet material having their sideportions bent inwardly to form overhanging flanges, guide member beingprovided with a cut out forming a passageway, a sash having one endportion pivotally mounted in said frame, and pivots connected with thefree end portion of said sash and adapted to pass through thepassageways of said guide into and out of engagement by the flanges ofsaid guides.

In testimony whereof I afliX my signature in presence of two witnesses.

FRANKLIN R. ESHBACH.
